In Day Color Palette, hard bottom will always be shown in bright yellow color. Soft bottom will consist of darker colors, and you will see more blue and red. 2. The thickness of the line representing the bottom is also an indicator of the bottom hardness, the thicker the line, the harder the bottom.
What does a school of fish look like on fish finder?
Fish species that form schools vary considerably when it comes to shapes and sizes, but the common element is that the fish finder display shows fish schools in a bulging or protruding fashion. Individual fish swimming about are very easy to identify since they have a very distinct boomerang or half moon shape.

What do the numbers on a transducer mean?
This number (or range of numbers) refers to the frequency of the sound waves produced by that particular transducer. As sound waves travel through tissue, some of them are absorbed or attenuated, and some are reflected back to the transducer to produce an image.

How do you read a sonar flasher?
The flasher displays the bottom of the lake, any cover present, your lure, and of course fish. Color indicates the size of the object on your sonar: Red = Large, Yellow = Medium, Green = Small. When you drop your transducer in the hole, the flasher will display the bottom as a large bar of red.
What does CHIRP mean in sonar?
CHIRP stands for “Compressed High Intensity Radar Pulse.” That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t. How’s that? CHIRP scans the water for fish similar to the way the seek function on your truck’s radio scans the airwaves for FM stations.
Is high CHIRP for shallow water?
High CHIRP (150 – 240kHz, 455/800kHz) is best for inland or freshwater fishing and depths less than 600 feet. Medium CHIRP (80 – 160kHz) scans larger areas faster but provides less detail than high CHIRP and is also best for depths less than 600 feet.
Low CHIRP or 50kHz—Lower frequency means higher power for deep-water fishing. Medium CHIRP or 83kHz—Specifically designed to give the widest coverage area, 83 kHz is ideal for watching a bait under the transducer in shallow water.
Is CHIRP 2d sonar?
CHIRP is an acronym for Compressed High Intensity Radar Pulse, and it’s not so much a new type of sonar, but rather a better way to process and display traditional 2D sonar. “CHIRP was developed by the Navy to provide better deepwater penetration,” Scott said.
What is the difference between sonar and CHIRP?
A traditional sonar transmits about one percent of the time, but CHIRP sonars transmit ascending pulses that are ten times as long in duration. They put dramatically more energy into the water column, 10 to 50 times more, even though CHIRP devices often transmit at lower peak power than traditional fishfinders.
How do you read a deep CHIRP 2?
What frequency is best for sonar?
As a rule of thumb, use frequencies below 140 kHz when fishing very deep water (over 1500 feet). Between 600 and 1500 feet, frequencies between 100 kHz and 160 kHz tend to work well. For anything 600 feet or shallower, you should use higher frequencies – over 160 kHz.
What frequency is fish attracted to?
The 100 to 200 Hz high frequency signal is particularly effective in calling far field fish sometimes believed located as far away as a mile or more, and sharks. The fish caller attracts salt water fish including sharks, tuna, yellow tail, black sea bass, tautog and red snapper.
These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source.
What is 2d CHIRP display frequency?
Whats better down imaging or sonar?
Side imaging generally may have a larger proportional range than down imaging sonar, while down imaging obviously wins as far as depth range. What is really helpful is that many manufacturers have released models that have both side and down imaging sonar, so you don’t have to make a choice between two separate units.
